Implement Configuration Management Databases that Deliver Rapid ROI and Sustained Business Value



Implementing an enterprise-wide Configuration Management Database (CMDB) is one of the most influential actions an IT organization can take to improve service delivery and bridge the gap between technology and the business. With a well-designed CMDB in place, companies are better positioned to manage and optimize IT infrastructure, applications, and services; automate more IT management tasks; and restrain burgeoning costs. Now, there's an objective, vendor-independent guide to making a CMDB work in your organization. The CMDB Imperative presents a start-to-finish implementation methodology that works and describes how the CMDB is shifting to the superior Configuration Management System (CMS).

Drawing on the experiences of hundreds of organizations, they present indispensable guidance on architecting and customizing CMDB solutions to your specific environment.
